Why Home Battery Storage Matters
In Canberra and surroundings, where solar feeds abundance during the day but electricity is needed around the clock, home batteries are essential. They help:
- Store surplus solar for nighttime use 🌙
- Reduce electricity bills by load-shifting
- Provide backup during outages
- Support the grid through peak demand
